When you look at pictures and rub your lower body parts using lubricant. Also, when you have an erection and form a hole in your matress using only your genitals.
(Sometimes people may not use lubricant. Basically becuase they like it rough).
I love dinastricating to pictures of Trish and Lita every night.
